Connie Labetti worked on the 99th floor of the south tower — the second World Trade Center tower to be hit on Sept. 11, 2001.

She made it out of the building thanks to her boss, Ron Fazio. He, however, did not survive. Fazio was one of 176 Aon employees who died that day. He was 57.

"He's the reason I'm here, there's no question about it," 52-year-old Labetti says. "Most of us survived that day because of him."
